Understanding the Common Causes of Squealing Brakes
Squeaking and squealing brakes are often indicators of problems in the automobile. Therefore, you should not overlook this issue when reviewing the condition of your vehicle. In simple terms, you should remember that if the brakes in your car are compromised, you will experience handling trouble. This malfunction could, in turn, lead to lack of control when driving and result in serious road accidents. So, if you have noticed some strange noises coming from your vehicle during braking, here are the possible causes and their solutions.
Degraded Brake Pads
The most common cause of a squealing should from the brakes is worn-out pads. In general, modern brake pads are manufactured with a useful feature known as a wear tab. This tab is a metallic element which is inserted inside the pads. When the brakes wear away and deteriorate due to use, the wear tab will be exposed. As a result, when the brakes are engaged, this feature will produce the unpleasant noise. This component is essential for safety because it warns drivers that their brakes are in bad condition. Replacement of the brake pads will eliminate the squeal and restore the optimal functions of the system.
The auto braking structure is lubricated in several areas during installation. These areas include sliding surfaces like the calliper bolts, the backing plate and the calliper piston. This oiling practice minimises detrimental friction in the braking system. Unfortunately, the lubrication can wear off allowing, the frictional force to return. Consequently, a squeaking noise will be heard as metal surfaces rub against one another.
This problem can be solved easily by lubricating the surfaces to manage the friction. However, you should note that it is difficult to identify lack of lubrication without the disassembly of the brake callipers and wheels. Ideally, you should check the braking components for rusting. If there is corrosion deposit or distinctive dryness, you should restore lubrication.
Defective Brake Rotors
The brake rotors could be the cause of the noises coming from your vehicle. Typically, new brake rotors have smooth and flawless surfaces. However, the structure is worn down because of the pressure from the brake pads. Also, the friction causes the rotors to experience heating and cooling cycles. The changes in temperature and the general friction can cause the rock particles, brake pad pieces and debris to stick to the surface. You can identify the problem by removing the tyres and identifying the defects. If this is the case, you should hire a mechanic for clean-up and restoration.
